Sounds like you need planning permission, so an architect rather than a party wall surveyor.
I recommend Jack Dusek, he's good.
Once you have planning in place, then you'll need a party wall surveyor
Give Mr Party wall or watson woods a call
As you will see when googling, the company 'Mr party wall' has one of the best reputations around, offering the same fixed fees to all and a nationwide service.
Watson woods are also good.
Surveyors write there own fees into an award so always read reviews etc. If a company doesn't have any reviews, they either don't allow it or they've reset their profile.
I've already done the paperwork, but unfortunately one one side they've requested the full works (surveyor and all) but thanks for the suggestion! C
Hi Caitlin, we had a similar scenario, however both neighbours requested a surveyor to Act on their behalf. One neighbour agreed to an agreed surveyor and the other did not. We appointed a local surveyor who came recommended, very approachable and knowledgeable with a lot of construction and Building Surveying experience and in highnsight very good value for money (considering the cost of my neighbours surveyor, which our surveyor challenged and had reduced!).
I also tried to do it myself, you can indeed serve notice ( tell your neighbour of the proposed work) but cannot appointment yourself becuase of the inherant bias ( and lack of technical or legal knowledge lol).
I've always been a fan of local and recommended. Our neighbours expensive chartered surveyor (£200ph) was non existent all correspondence was leveraged through junior staff who attended to carry out an inspection with nothing but a grin and hand in pocket lol, at least use a camera or something!!!.
Go local go recommended. His name wasTarquin happy to pass on contact number (if site allows) they have a website www.tksurveyinggroup.co.uk which is where we submitted our plans.
Good luck either way, building work is always stressful (but worth it in the end )
